"Neither group uses iso 8601 because the big-endian enthusiasts were all at the meeting 20 years ago." As programmer and data wrangler, dealing with dates, holidays, and time zones is a challenge. In #rstats and #cpp but good libraries help. Happy to help a little too.

the CDC says it's not omicron unless it comes from the Omicrônne region of France, otherwise it's just sparkling covid

Please see the README below. Current #Rstats is used on @Ubuntu by thousands via `apt` from CRAN itself thanks to @marutterstat (and similar builds exist at CRAN for @Debian, @RedHat and @openSUSE). Come to the r-sig-debian list if you have questions. cloud.r-project.org/bin/linu…

Added bonus: A fairly strong guarantee that that code will run as is in a week, month, year, decade, and beyond. #rstats #baseR

It's amazing the things one can do in base R (without installing or loading any other #rstats packages):

You get artifacts (for "some time") from RHub and from win-builder, but you need to manually fetch and present them somewhere. Which a drat repo can do -- see my `drat` package and docs. Or you can use r-universe which does the build and drat-alike hosting for you off github.

"You can find a perfect correlation if you just control for the residual." The truth may well be unknowable but hey maybe your code runs ... so teaching / reasoning about statistical programming may be easier than actual modeling 😇 #rstats

I am delighted and deeply humbled that my dissertation has been awarded the 2022 Psychometric Society Dissertation Prize. I'm grateful to my advisor, Prof. Steven Culpepper, and my committee, who provided their time, support, and feedback leading to this moment.

Yes and we all laughed about it already in 2018. No real need to reheat this now. hbr.org/2018/10/prioritize-w…

Well of course. We all use them. But the *how* and *which* are ours choices, which may differ. You may have seen that I started this series of tweets with one on vignettes (and a blog post), followed by one on testing.

Yet it will break your CI setup. See the earliest comment and my comment there.

I use both measures (cf prior tweets). Today was a first with what I am now see as the "weight" of a package: its Suggests (which one may use along with it) and their hard dependencies. (Plot from my suggestion in github.com/DominikRafacz/dee… ) All work in progress, feeback is good.

So much yes! See eddelbuettel.github.io/r-ci for what I use and what is indeed successfully minimal.

"Dependencies are an invitation for other people to break your package." -- @joshua_ulrich Which of these two setups to query @PostgreSQL from #RStats looks more likely to take that invitation? (Disclaimer: I was the Google Summer of Code mentor helping create RPostgreSQL.)

"It depends." You can start with alightweight S3 class that inherits from data.frame, but has a print method also recognising your metadata. This is a actually a pretty neat use case to develop. Document what you do step by step. You'll have a tutorial in no time. #rstats

Congrats to @julia_edd for whom I just cooked up a storm to celebrate a little --- and hopefully we all can celebrate some more in May with the rest of the @Cornell Class of 2022.
Congratulations to #Cornell2022 December graduates. All of us at the Cornell Jeb E. Brooks School of Public Policy @Cornell are so proud of the work you have done and excited to celebrate your accomplishments! @CornellBPP

Idk have done advent of code day 1-15 in Rust now and I think it’s an interesting language but most of the type casting feels like security theatre on par with TSA
